ROTHENBERGER ROTEST GW 150/4 prístroj na detekciu úniku plynu a vody

For professionals who need to verify both gas and water pipe integrity on a single job, the ROTEST GW 150/4 eliminates the need to carry separate gauges. It combines two precision analog manometers in one portable unit: a Class 1.0 gauge for gas tightness testing up to 150 mbar and a Class 1.6 gauge for water pressure testing up to 4 bar. The integrated hand pump provides complete independence from electricity or compressed air, while the fine adjustment valve allows you to set exact test pressures without overshooting.

Highlights

• Dual-range testing: gas up to 150 mbar, water up to 4 bar
• Integrated hand pump – no external power or compressor required
• High-accuracy analog manometers: Class 1.0 for gas, Class 1.6 for water
• Quick coupling for gas connection and G 1/2" water connection (adapter for G 3/4" included)
• Fine adjustment valve, vent valve, and pressure relief valve for controlled testing
• Robust housing made of plastic and metal for demanding job site conditions
• Compliant with DVGW TRGI for gas and DIN 1988 for water installations

In daily use

On a typical gas installation job, you connect the ROTEST GW 150/4 via the quick coupling, pump up to the required test pressure, and monitor the analog manometer for any drop over the prescribed test period. The fine adjustment valve lets you hit exact pressure values without overshooting, while the pressure relief valve safely vents the system after the test. For water lines, screw the G 1/2" connection onto the pipe (using the included adapter for G 3/4" if needed), pump to the desired pressure, and check for leaks. The hose length of 1.5 m gives you flexibility in positioning the device. The analog manometers are easy to read and provide reliable readings even in bright sunlight or dusty environments, making this tool a dependable companion for daily use on construction sites.
